A page’s history shows you the entire timeline of changes to the guide. You can even revert back to any previous state. To see the revision history, click the "History" tab in the upper right corner of the guide. From here, you can view all of the recent editing activity on a specific page. The history view also shows contribution statistics.

On all guide pages, there is a "Browse past guide revisions" section. This tool allows you to view and revert to old editions of the guide.

To view a screenshot of or revert to an older guide:

Click the "changes over time" link. This will take you to a page with the most recent version of the guide page and a drop down menu in the top right.

To view one edit earlier or later, you can click "Newer" or "Older." If you want to view a specific date and time, click on the drop down menu and select the desired date. These will pull up snapshots of how the page looked after the edits at that time and date.

If you want to revert the page back to the date selected, you can click the "Revert to this version" button after selecting a date.

This creates a new live version of the guide that is a copy of the version you are reverting to. This means that you do not have to worry about losing any recent edits. If the current version is from September 13th, and you revert the guide to the version from September 9th, it will copy the September 9th version and make it into a new version with the current date, say September 22nd. Want to go back to the September 13th version? Simply select it from the drop-down menu and revert to it.

If public editing is enabled on your site, you will see a section under a guide's history titled "Guide Ownership". In this section, you can see exactly how much people have contributed to the final document. This distribution is updated periodically. It does not update immediately after each change.

Every profile that has contributed a significant amount of information to this page will appear here with the percentage of the page that they added. This takes into account creating steps, uploading pictures, etc. If this is a guide page, the Reputation awarded from successful completion of this guide is split proportionately between all contributors to the page based on this percentage.

It is possible to create an exact copy of a guide you've already written. To do so, go to your management console. Next, click content and navigate to the "'Guide Duplicator'" tab. Locate the guide ID number for the guide you want to duplicate. Enter the Guide ID into the text box and hit "Duplicate". A link to your new guide will appear on the right.

Note: if you are duplicating a guide that contains prerequisites, make sure to check the "'Inline Prerequisite Guides" box.

On any category page, there will be a section titled "Category History." This section does not allow for any revisions, but it will show you all of the categories that the current category has been placed in over time.

A Wiki's history shows you the entire timeline of changes to that wiki. To see the history of a Wiki, click the "History" tab in the upper right corner of any document. From here, you can view all of the recent editing activity on a specific page.
